I was referring to the results of the IAEA delegation to Japan:
“TOKYO, May 25 (Xinhua) — A delegation of nuclear experts from the International Atomic Energy Agency visiting Japan on a fact- finding mission to establish the cause of the nuclear disaster at the Fukushima No. 1 nuclear power plant, the worst since the 1986 Chernobyl crisis, said Wednesday that their investigations are on “behalf of the world” and will be fair and objective.”
Upon return they had this closed door session wherein they said they were unable to get the information needed.
According to the article, upon returning from their fact-finding mission, they had a closed-door meeting where they said one of the FACTS they had FOUND was that people couldn’t get the information they needed during the initial stages of the crisis.
There is nothing in the article you posted which suggests the IAEA’s fact-finding mission was hampered by a lack of information. It might have been, but that wasn’t in the article you posted.
